REGENTERING DEVICE.

Application filedOctober' 12, 1921, SeriaLNo 507,303.

T0 all whom it may concern:

Be it known that T, H NRY Kn'r'rLnR, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Recentering Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to boring implements and has for an object to provide a new and improved type of device for recentering locomotive drivers.

A further object of the invention isto provide a re-centering device having improved means for attaching to and operating upon a driver.

A further object of the invention is to provide a plate or supporting member with means for attaching to a driver with a sleeve in axial alinement with the axis of the driver and improving means for co-acting with said supporting member for boring axially of said driver.

With these and other objects in view the invention comprises certain novel elements, parts, units, combinations, mechanical movements and functions, as disclosed in the drawing, together with mechanical equivalents thereof, as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a diametrical sectional view through the device and through a conventional driver;

Figure 2 is a view of the device in side elevation upon a driver also shown in side elevation;

Figure 3 is an enlarged detail sectional view showing the means of attaching the device to the driver;

Figure 4 is a View in elevation of the supporting member seen from the side, operatively held next to and in contact with the driver;

Figure 5 is a perspective view of the end of the boring tool and centering bit, and

Figure 6 is a perspective view of the attaching member.

Like characters of reference indicate corresponding parts throughout the several views.

For attaching to the side of and in proper operative relation with a driver, indicated conventionally at 10, a plate or fixture 11 is provided having a bore 12 registering with andforming a part of the bore of the sleeve 13 which extends perpendicularly to the face of the fixture 11 at the side opposite that engaging the driver.

To secure this fixture 11 to the driver hooks 14 are employed having shanks 15 which extend through slots 16 in the fixture 11 for the purpose of adjustment. The shanks 15 are screw-threaded, as indicated more particularly at Figures 1 and 3, and nuts 17 are employed upon the screwthreaded portions for the purpose of exerting tension upon the shanks l5 and hooks 14 to clamp the device against the driver. Means for properly spacing the fixture 11 from the face of the driver is provided in the lugs 18, any number of which may be formed upon any convenient part of the face of the fixture at the side indicated at Figure 4.

From this it will be seen that it will be possible and convenient to apply this to the driver 10 with the bore 12 absolutely in alinement with the axle 19 of the driver, as shown at Figures 1 and 2.

Within the bore 12 and sleeve 13 the shank 20 of a boring tool is accommodated having a boring head 21 and centering point 22, although it is to be understood that the exact formation of this boring extremity, including the head 21 and point 22, forms no essential part of the present invention, which includes the use of any type of boring head which is found desirable.

The sleeve 13 is screw-threaded, as indicated at 23 and a thimble 24 internally screw-threaded is employed thereon having an opening axially in its end to accommodate the shank 25 of the boring tool forming a shoulder at 26 so that the rotation of the thimble 24 upon the threads serves to feed forward the boring tool.

Power is applied to the shank 25 in any approved manner, at Figure 2 a crank 26 being shown, it being understood, however, that this crank is intended only to indicate that power is applied and not limiting it to the application of power in such manner, which may be either manual or mechanical.

In operation the device will be secured to the side of the driver with the centering bit 22' properly engaging the exact center of the axle 19 and will be clamped so that the boring tool 20 is in axial al'mement with the axle. Having been clamped firmly in this position the thimble 24 is manipulated to move forward the boring tool Which is manipulated by application of power thereto in any approved manner, to rotate it as advanced. In this manner the re-centering will be accomplished promptly and efliciently.

What I claim is:

The combination Witha boring tool of a sleeve forming a journal for said to0l,"a

plate carried rigidly by the sleeve With its planeperpendicular to the axis of the tool,

means to attach the plate to the Work at variable dlstances from said axis, and means tospace the plate away fromand in parah lelism With the Work," both of said means being located between the plate and the orkto provide an; unobstructed space in front of the plate to facilitate the placing ofthevvork.

In testimony WhereofI hereunto affix my signature in presence of two Witnesses.

HENRY KETTLER.
